SnO2-core carbon-shell composite nanotubes with enhanced photocurrent and photocatalytic performance

Facet-controlled synthesis and facet-dependent photocatalytic properties of SnO2 micropolyhedrons

“…According to the EIS results in Fig. S7b, the diameter of the semicircle in the Nyquist plot, which represents charge-transfer resistance [7,19], decreases from sample 1 to 3, indicating that the increase in the ratio of the exposed {1 0 1} facets can significantly reduce the recombination rate of the photogenerated electrons and holes.…”

“…Among the various metal oxide materials, SnO 2 has attracted much attention especially in the fields of gas sensors [1], dye-based solar cells [2], lithium-ion batteries [3], supercapacitors [4], transparent conducting electrodes [5], catalyst support [6][7][8], and photodetector [9]. It has been shown that controlling the exposed facets during synthesis is an effective method to tailor the functionalities of various materials [6][7][8][9][10][11][12][13][14][15][16][17][18][19]. However, the surface-dependent properties of SnO 2 have not been studied as extensively, possibly due to the practical difficulty in obtaining SnO 2 structures with the desirable surface characteristics.…”

Synthesis, Characterization and Photocatalytic Performance of SnS Nanofibers and SnSe Nanofibers Derived from the Electrospinning-made SnO2 Nanofibers

“…Double-crucible technique has been proved to be an efficient, convenient and simple way to fabricate nanofibers, nanobelts and hollow nanofibers 24 . Meanwhile, electrospinning is a promising, straightforward and convenient way to prepare one-dimensional (1D) nanomaterials [25][26][27] with diameters ranging from tens of nanometers up to micrometers owing to its easy control and low cost, including nanowires 28 , nanobelts [29][30][31] , core-shell structured nanofibers [32][33][34] core-shell structured nanotubes 40,41 , etc. Nevertheless, the fabrication of SnS or SnSe nanofibers via electrospinning combined with a double-crucible technique is not reported.…”

A new route to fabricate PbS nanofibers and PbSe nanofibers via electrospinning combined with double-crucible technique

“…Double-crucible technique has been proved to be an efficient, convenient and simple way to fabricate nanofibers, nanobelts and hollow nanofibers [24]. Meanwhile, electrospinning is a promising, straightforward and convenient way to prepare one-dimensional (1D) nanomaterials [25,26] with diameters ranging from tens of nanometers up to micrometers owing to its easy control and low cost, including nanofibers [27,28], core-shell structured nanofibers [29,30], core-shell structured nanotubes [31,32], nanowires [33], nanosheets [34,35] and nanobelts [36][37][38], etc. Nevertheless, the fabrication of PbS or PbSe nanofibers via electrospinning combined with a doublecrucible technique is not reported.…”
